Our platform indexes, curates, annotates, and evaluates data across the full AI lifecycle, from development through production.\nTrusted by Woven by Toyota, AXA, UiPath, Zipline, and more. We're an ambitious team of 100+ working at the frontier of AI and have raised $60M in Series C funding from Wellington Management, CRV, Next47 and Y Combinator.\nThe role\nWe're building tools for the full Physical AI data stack - from data acquisition, through ingestion and curation at scale, to 3D rendering, annotation, and verification. You'll solve problems of large-scale efficient data transfer and storage, complex domain modelling, applying the latest machine learning models, and squeezing performance out of web browsers.\nYou'll work with the biggest names in robotics and autonomous vehicles, and join a small, highly collaborative team at a crucial stage of accelerated development. You'll be a key driver of progress on a core part of our product, operating with a high degree of autonomy and crafting performant, reliable, and maintainable solutions at speed.\nWhat you'll do\nBuild and maintain high-performance frontend experiences, including rendering complex 3D scenes with thousands of objects at smooth frame rates\n\nWork across the full stack - from backend data pipelines and storage systems to frontend visualisation and interaction\n\nTake end-to-end ownership of projects, from product and architectural decisions through to deployment, monitoring, and measuring user impact\n\nWork with visual, spatial, and sensor data to make sense of the physical world\n\nTackle complex domains at massive scale using simple, well-crafted solutions\n\nTake initiative, be proactive in problem-solving, and continuously seek improvements\n\nWho we're looking for\nExperienced: you've seen a lot and built a lot - personally developed and maintained multiple systems from scratch, with a deep understanding of the trade-offs involved in building reliable, performant software at speed\n\nAt home with challenging frontend work: you're comfortable rendering complex 3D scenes, working with spatial and sensor data, and optimising for browser performance\n\nImpact-driven: you want your work to have a tangible outcome for people and aren't satisfied by products that don't see the light of day\n\nA builder: you enjoy all aspects of building a complete product, are comfortable moving across the stack, and love problem-solving from first principles\n\nComfortable with uncertainty: happy to tackle problems without a predefined solution, and excited to make decisions autonomously as you go\n\nA team player: you contribute your best work and actively help others do the same - you enjoy levelling up those around you\n\nExperience requirements\nStrong full-stack engineering experience, with a particular strength in complex, high-performance frontend work\n\nExperience with 3D rendering, WebGL, or similar technologies for visualising spatial/sensor data is a strong plus\n\nProficiency in Python and/or TypeScript; experience with React a plus\n\nFamiliarity with cloud infrastructure (GCP preferred) and containerised deployment (Kubernetes)\n\nExperience in robotics, autonomous vehicles, or Physical AI is a plus\n\nTech stack\nWe are technology agnostic at Encord and not looking for experience across all of these - as long as you're open to learning, please apply.\nWhy Encord\nCompetitive salary, commission, and meaningful equity in a high-growth startup\n\nStrong in-person culture - most of the team works from our London office 4+ days/week\n\n25 days annual leave + UK public holidays\n\nAnnual learning & development budget\n\nTravel for customer visits, events, and conferences across the UK and Europe\n\nCompany lunches twice a week\n\nMonthly socials & bi-annual team offsites","description_format":"text","description_chars":3860,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Annual leave","Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["MLOps","AI Training Data & Annotation"],"lifecycle":[{"event":"open","at":"2026-08-27T16:51:18Z"}],"visa":[],"liveness":{"score":35,"band":"fade","label":"Fading","p_open":1,"p_active":0.643,"p_room":0.55,"age_days":50,"expected_fill_days":36,"reasons":["conf:1","win:tail"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/encord-senior-full-stack-engineer-physical-ai-3","json_url":"https://alion.io/job/encord-senior-full-stack-engineer-physical-ai-3.json","meta":{"generated_at":"2026-10-19T01:21:03Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":624,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-20T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":557},"rest":"https://alion.io/mcp/rest/get_company?id=557"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fencord-senior-full-stack-engineer-physical-ai-3"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fencord-senior-full-stack-engineer-physical-ai-3"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fencord-senior-full-stack-engineer-physical-ai-3"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/encord-senior-full-stack-engineer-physical-ai-3\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fencord-senior-full-stack-engineer-physical-ai-3"}]}
